Mass spectrometer calibration of Cosmic Dust Analyzer

Design, Construction and Calibration of a Laser Ionization Time-of-Flight Mass Spectrometer

A time-of-flight mass spectrometer (TOF-MS) developed in our laboratory at Isfahan University of Technology is described here. The TOF-MS instrument uses laser as the ionization source which provides an opportunity to investigate the ions formed in laser ablation or desorption. The TOF-MS has an ionization chamber containing an accelerator and an ion lens to focus the ions into a one meter line...

The Dustbuster: A Compact Time-of-flight Mass Spectrometer for Cosmic Dust Analysis

Hypervelocity microparticle impact studies using a novel cosmic dust mass spectrometer

Micron-sized iron and copper particles accelerated to 2-20 km/s in a 2 MV Van de Graaff electrostatic accelerator tested the performance of our recently-developed cosmic dust mass spectrometer. This compact in situ dust analyzer, known as the Dustbuster, is designed to determine the elemental composition of cosmic dust particles through impact ionization and subsequent time-of-flight mass spect...

Dustbuster: a compact impact-ionization time-of-flight mass spectrometer for in situ analysis of cosmic dust

We report on the design and testing of a compact impact-ionization time-of-flight mass spectrometer for analysis of cosmic dust, suitable for use on deep space missions. The instrument, Dustbuster, incorporates a large target area with a reflectron, simultaneously optimizing mass resolution, particle detection, and ion collection. Dust particles hit the 65-cm target plate and are partially ioni...
